Abstract

Kulit singkong merupakan limbah dari industri tepung tapioka yang belum dimanfaatkan dengan maksimal. Padahal kulit singkong ini mempunyai kandungan gizi yang tidak kalah dengan singkong nya, sehingga mempunyai potensi untuk dimanfaatkan dengan cara diolah menjadi tepung. Pemanfaatan tepung kulit singkong sebagai bahan pangan terkendala dengan karakteristik bahan yang tidak memenuhi kebutuhan untuk dibuat menjadi produk tertentu. Oleh karena itu diperlukan proses modifikasi sebelum dapat dimanfaatkan secara maksimal sebagai bahan produk makanan. Salah satu metode modifikasi tepung adalah dengan Heat Moisture Treatment (HMT). Tujuan dari penelitian ini adalah untuk menganalisa pengaruh suhu dan lama waktu perlakuan HMT pada tepung kulit singkong terhadap sifat kelarutan dan swelling power. Teknik Heat Moisture Treatment dipakai untuk memodifikasi tepung kulit singkong ini agar tepung yang dihasilkan menjadi lebih baik lagi, dengan variable suhu 90oC ,100oC ,110oC dan lama pemanasan 1 jam, 2 jam, 3 jam, 4 jam, 5 jam, dengan kadar air awal 28%. Kemudian dilakukan analisa swelling power, sollubility dan analisa proksimat, dari hasil analisa didapatkan hasil swelling power dan sollubility nya menurun dari tepung kulit singkong alami. Hasil solubility dan swelling power terendah yang diperoleh pada penelitian ini diperoleh pada suhu 1000C waktu 5 jam dengan solubility sebesar 6% dan swelling power sebesar 9,4.

Abstract

Children's creativity must be encouraged from a young age in order for them to reach their full potential. There are several techniques to encourage children's creativity; one of them is to create eco-bricks. This exercise will educate youngsters how to recycle trash and create new objects based on their imaginations. The preceding research makes use of classroom action research, which is conducted in four stages: preparation, implementation, observation, and reflection. This implementation resulted in an increase in children's creativity from 40% pre-cycle to 65% in cycle one, which increased to 85% in cycle two.

Abstract

The development of STEM-based mathematics learning modules that are systematically arranged using the PBL (Problem-Based Learning) model is one way to train students' higher-order thinking skills (HOTS). This study aims to describe the process, validity, and practicality of the developed mathematics learning module and determine the students' higher-order thinking skills after using the mathematics learning module using the development research type. This STEM-based mathematics learning module with the PBL model was developed referring to the ADDIE development model, which consists of 5 stages, namely: (1) Analysis, (2) Design, (3) Development, (4) Implementation, and (5) Evaluation. The math learning module focuses on statistical material on the size of data concentration given to class VIII students at UPT SMPN 9 Gresik, as many as 31 students. Implementation begins with analyzing the results of instrument validation by validators, then analyzing student response questionnaires filled out by students after using the learning module and through higher-order thinking skills tests. Based on the results of the development process, it can be concluded that students still have difficulty working on higher-order thinking skills at the initial stage, namely the analysis stage. Designing and making modules are carried out at the design stage and development stages. At the implementation stage, the module was tested and declared feasible by the validator. The last stage is the evaluation stage, namely analyzing the data that has been obtained. The results of the validation of this math learning module are in the very valid category, with an average total validity (RTV) value of 4.16 by the three validators. The math learning module was also declared practical in theory with an average score of B, with the provision that it could be used with minor revisions. Practically, it gets an average score of 77.64% in the category of higher-order thinking skills, 19 students in the very good category, 7 students in the good category, and 5 students in the moderate category. Thus, The STEM-based mathematics learning module using the PBL model could been said to be well used to improve students’ mathematical understanding and higher-order thinking.

Abstract

Understanding of cube and cuboid concepts is one of the essential goals of solid geometry learning. Most studies of students’ understanding of these concepts have posited a gap between the students’ surface area and volume conceptions of its and students’ understanding. The study aims to describe the students’ mental constructions in APOS (Action, Process, Object, and Schema) theory framework. This study used analysis of students as subject to three junior high school students who have differences in mathematical abilities with a qualitative approach. Data were collected by the task sheet and interview. The result of this study evidences that subject who has high mathematical ability could solve problems about cube and cuboid concepts correctly in the action stage. In the process and object stage, subject could provide detailed explanations of how steps to assess the surface area and volume of cube and cuboid. She compared two shapes with different sizes of cube and cuboid. In the schema stage, she made systematic understanding related to the concepts of surface area and volume of cube and cuboid. The subject who has medium mathematical ability explained her mental construction in action and process stage well, despite the error in the process stage. Next stage, she had compared two different shapes of cube and cuboid to found their ratio. The last stage, she had not completed her explanation. The subject has low mathematical ability could solve the problems about cube and cuboid concepts. At the process, object, and schema stage, she had not completed its indicators to show cube and cuboid concepts.
